Does anyone make a replacement rear express style sight for a Number 1 that drifts into the stock dovetail?
I don't really want to have to replace the quarter rib but if that's the way to go...
Does anyone make an island for express sights that would easily replace the quarter rib? (not too many more holes needed)

New england custom gun makes one that clamps on the rib and one for a dovetail.I have one on a #3 mounted on weaver base.I really like mine they have a website w/pics.Didnt see the express part when I originally posted. w/regards
